Howie Mandel InterviewHowie Mandel has been very busy. The 54-year-old stand-up comedy veteran became hot all over again hosting 'Deal or no Deal.' Last year, he wrote a New York Times best-seller, his alternately hilarious and bracingly-honest memoir 'Here's the Deal: Don't Touch Me,' touching on his often crippling obsessive-compulsive disorder. Now he's back on TV as the new judge on 'America's Got Talent,' replacing the formidable David Hasselhoff.

Mandel chats with PopEater about the state of his OCD, filling the Hoff's shoes and what he really thinks of the vicious Piers Morgan.
